Document Summary
Includes self-administered and interviewer-administered recalls that collect information on various aspects of physical activity. Proxy-reports involve someone else such as a parent or a care-taker reporting on behalf of another individual e. g. , child or elderly person. Quick and easy for large groups (low burden) Record detailed information about several dimensions of pa (e. g. , type, frequency, duration, intensity) and require participants to record their activities daily. Involves watching people objectively and noting specific behaviors and activities they are participating in. Quick and easy for small to medium size studies. Useful in community, school and workplace settings. Worn on the hip and assess the number of steps a person takes by responding to vertical forces: note: a pedometer senses your body motion and counts your footsteps. By knowing the length of your usual stride you can convert this count into distance. 10,000 steps per day is considered enough physical activity. Some pedometers measure many dimensions, but they are expensive.
